BLUE-MOVED VALVE.

Specification of Letters Patent.

Patented July at, isle.

To all whom it may concern:

Be it known that I, GEORGE S. Powna, a citizen of the United States, andresident of N utley, in the county of Essex arid State of New Jersey,have invented certain new' and useful Improvements in Fluid-MovedValves, of which the following is a specification.

This invention relates to a fluid moved valve, which is particularlyapplicable to a reciprocating pistonand cylinder. Its organizationcomprises a valve with a pair of members each of which comprise at leastone conical trust-um, the-surfaces of which are reversed to each other.The said frustums have impinged thereon an actuating fluid,

the longitudinal components of the impulses of the actuating fluid,augmenting the reciprocations' of said valve. The valve principallyreceives its reciprocations from the eiiect of the flow of the fluidthrough the contracted area between its outer periphery and the ,top,bottom and side walls of the chamber in which it reciprocates as will beexplained.

In the accompanying drawings Figure 1 represents a top plan view of acylinder and its appurtenances with the invention incorporatedtherewith, Fig. 2 shows a partial section of Fig. 1 on the line 2, 2,Fig. 3 is a section as on the line 3, 3 of Fig. 2, Fig. 4-

represents a partial section of Fig. 2 on the line 4, 4 and Fig. 5 showsan enlarged longitudinal section of a modification of the invention.

A cylinder is indicated at 20 with the longitudinal port 21 having theinlet end 22 and outlet end 23, the longitudinal port 2&-

having the inlet end 25 and the outlet end 26, the exhaust port- 27 withthe threaded :portion 28 and the exhaust port 29 with the threadedportion 30. I

A back cylinder head is shownat 35, and a front cylinder head 36 hasformed there with a stufing box 37 with the gland 38. A piston 40 insaid cylinder has extending the piston rod 41 which extends through thevstufing box 37 and gland 38 in the usual manner. A main driving fluidsupply port 44 has connected thereto the driving fluid supply pipe 45. Avalve chest 47 with the central port 48 is bolted to the cylinder 20 bymeans of the bolts 49. The

valve chest 47 has in threaded engagement therewith the cylinder heads'50 and 51.

The cylinder head 50 has formed therewith detachable units of this withthe head 68 and nut 69 located and supported in the axial centers of thevalve chest 47 and cylinder heads 50 and 51.

Upon the guide bolt 67 is slidably supported a valve with oppositelypositioned conical frustums. Specifically the valvecomprises two memberswith the reversed positioned conical frustums 70 and 74. Against thelarger end of the frustum 70 is located the projecting collar 72 withthe conical frus-' tum 71 and collar 73. Against the larger end of thefrustum 74 is located the projecting collar 76 with the conical frustum75 and collar 7 7 A sleeve 80 separates the two members or frustums 70and 74 of the valve.

In the modification shown in Fig. 5 the members of the valve comprisedetachable units and consist of the supporting barrel 85 with the head86. The barrel supports the detachable conical frustums 87 and 90.Against the larger end of the frustum 87 is located the projectingcollar 89 with the conical frustum 88. Against the larger end of thefrustum 90 is located the projecting collar 92 with trust-um 91. Asleeve' 93 separates the frustums 87 and 90, and a locking collar 94 inthreaded engagement with the barrel 85, looks all the elements securelyon said barrel. The object of the modification is to be enabled todispense with some of said units or to vary their dimensions. Forinstance, the primary essential units of the valve are the proiectingcollars 72 and 76, in the form of valve shown particularly in Fig. 2 andthe projecting collars 89 and 92 shown in Fig. 5. In Fig. 2 all theother elements of the valve except the collars 72, 76 and the slwvo 80or its eqaivalent mightbe dispensed with, and in El 5 all the elementsof the valve except t e collars 89', $2 and some connecting meansbe-dispensed with.
